Looking for siblings & parents of Margaret (Willets) b. ca. 1750/51 in or near Berks Co.,Pa. married in a Quaker M.M. (which one?) ca. 1775 to William Custer, son of Paul & Sarah (Ball) Custer.
Think she had a brother Amos Willets b. 1753 d. 1795 whose wife was Dinah Rees, but some people have Amos has her father, but he was only about 2 or 3 yrs. older than Margaret.
Margaret had a son Amos Custer, so she names him after her brother Amos?
